linux/vt_buffer.h: allow either builtin or modular for macros
[ Upstream commit 2b76ffe81e32afd6d318dc4547e2ba8c46207b77 ]
Fix build errors on ARCH=alpha when CONFIG_MDA_CONSOLE=m.
This allows the ARCH macros to be the only ones defined.
In file included from ../drivers/video/console/mdacon.c:37:
../arch/alpha/include/asm/vga.h:17:40: error: expected identifier or '(' before 'volatile'
17 | static inline void scr_writew(u16 val, volatile u16 *addr)
